A Laboratory Experiment Using Molecular Models for an Introductory Chemistry ClassShahrokh GhaffariPresents a new approach to using molecular models in teaching general chemistry concepts. Students construct molecular models and use them to balance simple chemical equations, demonstrate the law of conservation of mass, and discover the relationship between the mole and molecules and atoms.Ghaffari, Shahrokh.

Interactive Demonstrations for Mole Ratios and Limiting ReagentsCrystal Wood and Bryan BreyfogleThe objective of this study was to develop interactive lecture demonstrations based on conceptual-change learning theory. Experimental instruction was designed for an introductory chemistry course for nonmajors to address misconceptions related to mole ratios and limiting reagentsWood, Crystal; Breyfogle, Bryan. J.

Procedure for Decomposing a Redox Reaction into Half-ReactionsIlie Fishtik and Ladislav H. BerkaThe principle of stoichiometric uniqueness provides a simple algorithm to check whether a simple redox reaction may be uniquely decomposed into half-reactions in a single way. For complex redox reactions the approach permits a complete enumeration of a finite and unique number of ways a redox reaction may be decomposed into half-reactions. Several examples are given.
